摘要

A bypass flow channel that bypasses part of an adsorbent is provided between an engine-side port and an atmosphere-side port in a gas flow channel of a canister body. Furthermore, a flow rate increasing member that increases the ratio of flow rate in the bypass flow channel when the flow velocity of a gas at the time of purge has exceeded a predetermined value is provided.
